Title: Method and apparatus for calibrating a laser wavelength control mechanism
Inventor: FOMENKOV IGOR
IPC: G01J3/28
Filed: 1994-08-31
Abstract: Calibration of a wavelength adjustment mechanism (104) of a laser is achieved using a hollow cathode absorption lamp (114). The lamp is provided with a vaporous material having a precisely known wavelength of maximum absorption. A  photo-detector (130) detects the amount of light from the laser beam absorbed by the vaporous material as a function of wavelength. The wavelength of the laser is adjusted to achieve maximum absorption such that the actual laser beam wavelength may be compared with an expected wavelength to determine a calibration offset. The hollow cathode lamp (114) is operated to produce a vaporous material of known absorption characteristic but is illuminated at a level substantially below a level required for conventional opto-galvanic resonance.

Abstract: La présente invention concerne un fourreau de lame muni d'un cran de sûreté (36, 37) destiné à empêcher le retrait par accident ou par inadvertance de la lame (27) lorsqu'elle est totalement engagée dans le logement du fourreau (1). Le dispositif de verrouillage, qui réagit automatiquement à l'introduction de la lame dans le fourreau, est de préférence associé à un aiguiseur de lame (19) qui réagit également aux mouvements d'introduction et de retrait de la lame dans le logement du fourreau. L'aiguiseur est de préférence au repos pendant l'introduction de la lame et opérant pendant le retrait de la lame. Le fourreau est pourvu d'un organe de dégagement (42) actionnable à la main, lequel organe permet de dégager le cran de sûreté pour extraire la lame, l'action sur l'organe de dégagement devant nécessairement être simultanée au retrait de la lame du fourreau. Une fois que la lame a été extraite d'une certaine longueur depuis la position d'engagement total, le cran de sûreté reste complètement dégagé, et dès lors, il n'y a plus à agir sur l'organe de dégagement, et il n'y a plus d'obstacle au retrait de la lame. Un organe de maintien de la lame (21) coopérant avec la lame empêche le retrait lorsque le cran de sûreté est complètement engagé. Cet organe de maintien peut être monté sur pivot sur le logement du fourreau, associé avec l'aiguiseur, de façon à être mis en fonction ou hors fonction par pivotement.

IPC: A61J1/06
Filed: 1995-10-31
Abstract: Des fermetures élastomères, telles que des bouchons de flacons pharmaceutiques, sont revêtues, par polymérisation du plasma, d'un alcane inférieur afin de réduire le coefficient de friction de la fermeture et de faciliter, par conséquent, la manipulation de ces fermetures. L'application du revêtement à une vitesse de polymérisation lente limite les effets défavorables du revêtement sur la résistance aux fuites du bouchon. Les bouchons (80) sont soumis à un gaz d'alcane inférieur dans un tambour rotatif (10) qui peut également osciller suivant un arc. Une bobine hélicoïdale (58) produit une énergie radioélectrique suffisante pour former un gaz de plasma faible provenant de l'alcane inférieur qui se polymérise sur les bouchons lors de la rotation du tambour.
Patent CA-2203295-A1 (CA)
Title: High efficiency method for isolating target substances using a multisample separation device
Inventor: BRISCO PAULA R G
IPC: C12Q1/6806
Filed: 1995-09-18
Abstract: Methods for separating target particles from a test medium in which the particles are suspended. The method contemplates utilization of blocking or masking particles which block or mask unwanted biological debris which tends to interfere with formation of complexes by which the target particles can be isolated. After centrifugation, the masking particles create a barrier between unwanted debris and test medium containing the target particles which permits the particles to be manipulated or modified without removing them from the debris. In a preferred aspect, magnetic separation techniques are used. In this aspect, non-magnetic 0.04 micron carboxylated polystyrene blocking particles are employed.

Patent CA-2228834-A1 (CA)
Inventor: GLADYSZ DARREN
IPC: B27C5/04
Filed: 1998-04-16
Abstract: Fences and guides presently designed for routers and router tables only permit materials to be fed either at a 0 or 90 degree angle to the longitudinal axis of the router bit.  Prior to this invention, the only method devised to rout a profile at an angle other than 0 or 90 degree to the longitudinal axis of the router bit was to pivot the router along an axis perpendicular to the longitudinal axis of the router. In the present invention, the fence which guides the workpiece perpendicularly to the longitudinal axis of the router bit can be adjusted for any angle between 0 and 90 degrees, thereby permitting the workpiece to be fed at any angle from 0 to 90 degrees to the longitudinal axis of the router bit. This invention permits adjustable angles of feed of the workpiece and thereby permits the obtention of numerous angles of cuts and profiles from a single router bit. Furthermore, the guide can also be moved closer or further from the router bit, and thereby permits the obtention of a profiled cut at various distances from the edge of the workpiece.

Patent CA-2233686-A1 (CA)
Title: Plasma panel exhibiting enhanced contrast
Inventor: WEBER LARRY F
IPC: G09G3/288
Filed: 1996-11-15
Abstract: A plasma panel, incorporating the invention, includes circuitry for applying row signals sequentially to a plurality of row electrodes. Each row signal includes a set-up period, an address period and a sustain period. A row signal during the set-up period includes both a positive-going ramp voltage and a negative-going ramp voltage, both ramp voltages causing a discharge of each pixel site along an associated row electrode. Both ramp voltages exhibit a slope that is set to assure that current flow through each pixel site remains in a positive resistance region of the gas's discharge characteristic, thus assuring a relatively constant voltage drop across the discharging gas, thus resulting in predictable wall voltage states. The set-up period thereby creates standardized wall potentials at each pixel site along each row electrode. Address circuitry applies, during the address period, data pulses to a plurality of column electrodes to enable selective discharge of the pixel sites in accordance with data pulses and in synchronism with the row signals.

Abstract: Life insurance methods, systems and products which revolve around having an insurance plan with at least two separate but related insurance contracts on the same insured or insureds. The contracts are developed using life insurance product data to develop tables from which death benefits and premium obligations, and usually cash values, are determined based upon an insured's gender, age and other risk factors.      The death benefits and premium obligations, and cash values, if any, are divided between the two or more contracts where more of the premium obligations are assigned to one or more of the contracts while more of the death benefits and cash values, if any, are assigned to one or more of the remaining contracts. Nonforfeiture and surrender provisions as well as typical riders can be added to one or all of the contracts.      The death benefits and cash values of the contracts are a function of the premium paid for all of the contracts.
